Improve desktop security by isolating Electron

Enable `contextIsolation` in Electron to securely expose a limited set
of Node.js APIs to the renderer process. It:

1. Isolates renderer and main process contexts. It ensures that the
   powerful main process functions aren't directly accessible from
   renderer process(es), adding a security boundary.
2. Mitigates remote exploitation risks. By isolating contexts, potential
   malicious code injections in the renderer can't directly reach and
   compromise the main process.
3. Reduces attack surface.
4. Protect against prototype pollution: It prevents tampering of
   JavaScript object prototypes in one context from affecting another
   context, improving app reliability and security.

Supporting changes include:

- Extract environment and system operations classes to the infrastructure
  layer. This removes node dependencies from core domain and application
  code.
- Introduce `ISystemOperations` to encapsulate OS interactions. Use it
  from `CodeRunner` to isolate node API usage.
- Add a preloader script to inject validated environment variables into
  renderer context. This keeps Electron integration details
  encapsulated.
- Add new sanity check to fail fast on issues with preloader injected
  variables.
- Improve test coverage of runtime sanity checks and environment
  components. Move validation logic into separate classes for Single
  Responsibility.
- Improve absent value test case generation.

 # Presentation layer
 
-Presentation layer consists of UI-related code. It uses Vue.js as JavaScript framework and includes Vue.js components. It also includes [Electron](https://www.electronjs.org/) to provide functionality to desktop application.
+The presentation layer handles UI concerns using Vue as JavaScript framework and Electron to provide desktop functionality.
 
-It's designed event-driven from bottom to top. It listens user events (from top) and state events (from bottom) to update state or the GUI.
+It reflects the [application state](./application.md#application-state) and allows user interactions to modify it. Components manage their own local UI state.
+
+The presentation layer uses an event-driven architecture for bidirectional reactivity between the application state and UI. State change events flow bottom-up to trigger UI updates, while user events flow top-down through components, some ultimately modifying the application state.

 ## Application state

+This project uses a singleton instance of the application state, making it available to all Vue components.
 
-[`StatefulVue`](./../src/presentation/components/Shared/StatefulVue.ts) functions include:
+The decision to not use third-party state management libraries like [`vuex`](https://web.archive.org/web/20230801191617/https://vuex.vuejs.org/) or [`pinia`](https://web.archive.org/web/20230801191743/https://pinia.vuejs.org/) was made to promote code independence and enhance portability.
 
-- Creating a singleton of the state and makes it available to presentation layer as single source of truth.
+Stateful components can mutate and/or react to state changes (e.g., user selection, search queries) in the [ApplicationContext](./../src/application/Context/ApplicationContext.ts). Vue components import [`CollectionState.ts`](./../src/presentation/components/Shared/Hooks/UseCollectionState.ts) to access both the application context and the state.
-- Providing virtual abstract `handleCollectionState` callback that it calls when
-  - the Vue loads the component,
-  - and also every time when state changes.
-- Providing `events` member to make lifecycling of state subscriptions events easier because it ensures that components unsubscribe from listening to state events when
-  - the component is no longer used (destroyed),
-  - an if [ApplicationContext](./../src/application/Context/ApplicationContext.ts) changes the active [collection](./collection-files.md) to a different one.
 
-📖 Refer to [architecture.md | Application State](./architecture.md#application-state) to get an overview of event handling and [application.md | Application State](./presentation.md#application-state) for deeper look into how the application layer manages state.
+[`UseCollectionState.ts`](./../src/presentation/components/Shared/Hooks/UseCollectionState.ts) provides several functionalities including:
 
-## Modals
+- **Singleton State Instance**: It creates a singleton instance of the state, which is shared across the presentation layer. The singleton instance ensures that there's a single source of truth for the application's state.
+- **State Change Callback and Lifecycle Management**: It offers a mechanism to register callbacks, which will be invoked when the state initializes or mutates. It ensures that components unsubscribe from state events when they are no longer in use or when [ApplicationContext](./../src/application/Context/ApplicationContext.ts) switches the active [collection](./collection-files.md).
+- **State Access and Modification**: It provides functions to read and mutate for accessing and modifying the state, encapsulating the details of these operations.
+- **Event Subscription Lifecycle Management**: Includes an `events` member that simplifies state subscription lifecycle events. This ensures that components unsubscribe from state events when they are no longer in use, or when [ApplicationContext](./../src/application/Context/ApplicationContext.ts) switches the active [collection](./collection-files.md).
 
-[Dialog.vue](./../src/presentation/components/Shared/Dialog.vue) is a shared component that other components used to show modal windows.
+📖 Refer to [architecture.md | Application State](./architecture.md#application-state) for an overview of event handling and [application.md | Application State](./presentation.md#application-state) for an in-depth understanding of state management in the application layer.
 
-You can use it by wrapping the content inside of its `slot` and call `.show()` function on its reference. For example:
+## Dependency injections
 
-  ```html
+The presentation layer uses Vue's native dependency injection system to increase testability and decouple components.
-    <Dialog ref="testDialog">
+
-      <div>Hello world</div>
+To add a new dependency:
-    </Dialog>
+
-    <div @click="$refs.testDialog.show()">Show dialog</div>
+1. **Define its symbol**: Define an associated symbol for every dependency in [`injectionSymbols.ts`](./../src/presentation/injectionSymbols.ts). Symbols are grouped into:
-  ```
+   - **Singletons**: Shared across components, instantiated once.
+   - **Transients**: Factories yielding a new instance on every access.
+2. **Provide the dependency**: Modify the [`provideDependencies`](./../src/presentation/bootstrapping/DependencyProvider.ts) function to include the new dependency. [`App.vue`](./../src/presentation/components/App.vue) calls this function within its `setup()` hook to register the dependencies.
+3. **Inject the dependency**: Use Vue's `inject` method alongside the defined symbol to incorporate the dependency into components.
+   - For singletons, invoke the factory method: `inject(symbolKey)()`.
+   - For transients, directly inject: `inject(symbolKey)`.
+
+## Shared UI components
+
+Shared UI components promote consistency and simplifies the creation of the front-end.
+
+In order to maintain portability and easy maintainability, the preference is towards using homegrown components over third-party ones or comprehensive UI frameworks like Quasar.
+
+Shared components include:
+
+- [ModalDialog.vue](./../src/presentation/components/Shared/Modal/ModalDialog.vue) is utilized for rendering modal windows.
+- [TooltipWrapper.vue](./../src/presentation/components/Shared/TooltipWrapper.vue) acts as a wrapper for rendering tooltips.

+# check-desktop-runtime-errors
+
+This script automates the processes of:
+
+1) Building
+2) Packaging
+3) Installing
+4) Executing
+5) Verifying Electron distributions
+
+It runs the application for a duration and detects runtime errors in the packaged application via:
+
+- **Log verification**: Checking application logs for errors and validating successful application initialization.
+- **`stderr` monitoring**: Continuous listening to the `stderr` stream for unexpected errors.
+- **Window title inspection**: Checking for window titles that indicate crashes before logging becomes possible.
+
+Upon error, the script captures a screenshot (if `--screenshot` is provided) and terminates.
+
+## Usage
+
+```sh
+node ./scripts/check-desktop-runtime-errors
+```
+
+## Options
+
+- `--build`: Clears the electron distribution directory and forces a rebuild of the Electron app.
+- `--screenshot`: Takes a screenshot of the desktop environment after running the application.
+
+This module provides utilities for building, executing, and validating Electron desktop apps.
+It can be used to automate checking for runtime errors during development.
+
+## Configs
+
+Configurations are defined in [`config.js`](./config.js).
